Flame retardant silicone ZY-8752 series and ZY-8750 series
General silicone rubber generally does not belong to flammable materials, but once the fire, will continue to burn down, although does not produce smoke and harmful gas, but in some of the need to increase security products, such as household appliances, office, machinery, aerospace, Marine, construction used in flame retardant silicone material, can prevent the occurrence of fire, flame retardant silicone rubber can be used for a variety of moulded products, such as: buttons, washer, packaging and other products.
